GEORGE F. SMITH, OF BUFFALO, NEW YORK.

. FLUSH-VALVE r 3 wATnR-oLosE'rs.

To all whom it may concern:

Be it known that I, GEORGEF. SMITH, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in lush-Valves for ater-Closets, of which the following is a specification.

My invention relates to improvements in valves for flushing-tanks, more specifically to float-controlled valves of that class.

The object of my invention is to provide a valve of the inverted type and a support and housing therefor constructed in such manner that the valve cushion or packing and the valve seat may be removed and replaced by unscrewing a single union which is readily accessible, and without any disturbance of the adjustment of the float-leverage; and thus enable an ordinary person to clean the valve, repack it, or smooth or replace the valve seat without other tools than an ordinary wrench and a pair of small pipe pliers. A further object is to afford a construction which may be attached to a standard tank and pipe of the upright type without removing the stand-pipe. These and other objects of my invention will appear more clearly from the following specifications and claim and from the drawings herewith, in which Figure 1 is a longitudinal vertical section I of a tank provided with my improvement;

and

Fig. 2 is an enlarged sectional detail showing the valve released for cleaning or repacking, as hereafter more fully described.

Fig. 3 is a transverse section on the line 3 3 of Fig. 1.

The intake pipe or stand-pipe 4 enters the tank from the bottom in the usual manner, and is secured therein in the usual manner. To this pipe are connected the elbow 5, the

nipple 6 and the elbow 7, and threaded into the elbow 7 is the valve seat casting 8, which carries threaded to it the annular valve seat 9 and which also carries the flange nut 10 by means of which the valve seat housing 8 is secured to the valve casting as now de- 7 scribed.

The valve housing consists of the chambase member 13 of the valve housing is screwj ustment.

threaded into the bottom portion of the chambered portion 11 of the valve housing and is bored to receive the body of the valve 11. This base member also has two oppositely positioned extensions or lugs 20 and 21, and to the extension 20 the arm 22 of the floatlS is pivoted, and to the lug 21 the arm 24 is pivoted.

Reciprocating within the valve housing is the valve 14. This valve 14: is bored transversely, as shown at 16 and this bore communicates with a vertical boring, which corresponds in diameter to the internal diameter of the discharge tube which is screwthreaded to, or otherwise secured to, the valve 1 1. The upper end of valve 14 is provided with the ordinary resilient packing, rubber or leather, shown at 17 and held in position by a ring or' sleeve l9.v The arm 24 which is pivoted to the lug or extension 21 on the base member 13 takes over the tube 15 and bears against the under side of the valve 14 as clearly shown in Fig. 1; and this lever 24- at its other end is link pivoted to the arm 22 of the float, which, as stated, is pivoted to the lug or extension on the base member 13.

The operation will at once he understood from the description just given; but the improvements attained by this construction are here particularly to be noted, namely; In the first place, by merely unscrewing the union 10, the entire housing and the float andlever connections may he slipped down without any disturbance whatsoever of the ad- An ordinary householder, unskilled in the plumbers craft, may thus repack the valve, smooth off the valve-seat if notched by rust slugs, or even put in a new valve seat with no other tools than a wrench and a pair of pliers. In the second place,

I this improvement may be attached to an ordinary standard tank having the ordinary upright pipe, without removal of the standpipe and the consequent probability of rupture of the tank lining in removing the stand-pipe.

While I am aware that valves of this class have heretofore been constructed and used, having a general similarity of appearance to my invention, I am not aware that it has been heretofore known that by the inversion and consequent arrangement of parts herein described, these ends and advantages have ever been attained.

Having thus described my invention, what 1 claim is:

In a tank valve, a valve seat element, a discharge pipe carrying at its upper end a tubular valve member having one end closed and provided with a valve element cooperating with said valve seat element, a flow chamber supported from said valve seat element, the remaining end of said pipe adapted to project below the minimum low fluid level in a tank whereby said pipe is always fluid sealed, and a laterally extending passage at the top of said valve member and of greater length than the diameter of the bore of said valve member and establishing communication between said pipe and said chamber whereby water issuing from said chamber must pass through said passage prior to discharge thereby eliminating all hissing noise of the fluid during operation of the valve.
